Fibre comes unstuck out: the ramie raw materials after the impregnation process pins down through feed roller (6) and feeds the fibre separating machine (3) that comes unstuck, and mix mouthful (37) at the particulate matter of this fibre separating machine that comes unstuck (3) and locate evenly to sneak into particulate matter (10), by carrying out mechanical presses in removal of impurities cylinder (31) and the fine workspace of coming unstuck out that many group worker rollers (32) form, rub, in length and breadth to opening fibre, make pectin substance progressively with fiber separation and removal, strip by shifting hairbrush (34) through the fine ramie raw materials of processing that tentatively comes unstuck out, pin down by transfer roller (7) and send into removal of impurities fibre separating machine (4).
5. ramie simple and fast mechanical degumming process according to claim 4 is characterized in that, in the described step (b), maceration extract is formulated by NaOH 4～6%(o.w.f), alkylbenzenesulfonate 0.3～0.5%(o.w.f); Impregnation technology is: bath raio 1:2.8～3,90～100 ℃ of injection liquid temperature, 8～12 hours resting periods.
6. ramie simple and fast mechanical degumming process according to claim 4, it is characterized in that, in the described step (d), concise liquid is formulated by NaOH 0.5～0.7%(o.w.f), sodium sulfite 0.1～0.2%(o.w.f), detergent 0.2～0.3%(o.w.f); Refining process is: bath raio 1:12,95～100 ℃ of temperature, 1.5～2 hours time.
7. according to claim 4,5 or 6 described ramie simple and fast mechanical degumming process, it is characterized in that, in the described step (c):
Fibre is opened in removal of impurities: after ramie raw materials enters removal of impurities fibre separating machine (4), acting in conjunction by removal of impurities hired roughneck (42) and removal of impurities screen drum (41), make the fiber band that enters oscillatory type removal of impurities screen drum (41) constantly be hit, throw, fall, shake off and remove the foreign material that stick on the fiber, and by the traction roller (8) in the place ahead with carry roller (9) to pin down and send into washing fibre separating machine (5), the mesh that foreign material see through removal of impurities screen drum (41) falls into the dirt chamber (43) that is positioned at its underpart, reuse after the particulate matter that falls (10) is collected and processes;
Fibre is opened in washing: after fibrage enters washing fibre separating machine (5), under the clamping of interior screen cloth (53) and outer net-cloth (54), the intersection that is subject to the inside and outside high-pressure injection current of spray equipment (56) is impacted and cleaning, fully remove pectin and foreign material, decompose fiber, and roll through dehydration pressure roller (57) and to remove the part rinse water; The particulate matter that washes out (10) sinks to washing fibre separating machine (5) bottom, is reclaimed after treatment reuse by retracting device (52).
